Lenovo Phab 2 Pro

First widely available Tango phone ; Reasonably priced for bleeding-edge tech ; Excellent battery life if you don't use Tango ; Reassuring build quality ; Fingerprint sensor works well

Tango is still a work in progress ; Huge size could be a deal-breaker ; Cameras are pretty lousy ; Lenovo's software is rough around the edges

The Lenovo Phab 2 Pro is an incredible thing, and it's just brimming with potential. It's also unpolished and frustrating to use a lot of the time. When the hardware and software don't come together as they should, it makes me wish Google and Lenovo...

Tango is fun when it works ; Interactive app experience ; No headset required for AR

Massive smartphone ; Tango is still half-baked ; Too few Tango apps right now

It’s a 3D world; we’re just living in it

First phone with Google Tango. Crisp Quad HD display. Fingerprint sensor, dual SIM, expandable storage, and dual-band Wi-Fi support.

Huge. Most Tango apps feel unpolished and lack compelling functionality. Subpar camera performance.

The colossal Lenovo 2 Pro is the biggest phablet we've reviewed in years, and one of the most unique. For $500 you get a crisp Quad HD display, promising AR functionality with Google Tango, and a premium build. But Tango still has some ways to go...

Good, high-resolution display ; High-capacity battery with excellent screen-on times ; Runs available Tango apps well

Will be much too big for many people ; Heavy, bulky, and slippery design makes drops more likely ; Middle-of-the-road hardware means shorter lifespan

All of this begs the question: is the Phab 2 Pro worth it? Considering the hardware the phone offers and the current state of Tango, I’d only say it is if you’re the kind of person who wants to be right there at the starting line as a new technology...

dual-SIM with support for U.S. GSM 4G bands ; well-made and rigid aluminum chassis ; generally cool surface temperatures ; fast-charging Micro-USB port ; great speakerphone quality ; large 6.4-inch QHD display ; fast CPU performance ; integrated Tango

non-removable battery; average battery life ; awkward positioning of fingerprint reader ; no NFC, USB Type-C, or wireless charging ; display colors could be more accurate ; large and heavy; over 10 mm thick ; average display response times ; average...

The big selling point of the Phab 2 Pro is its unique Tango hardware. At its current state, however, the feature is more of a novelty than it is a practical implementation. Aside from its gaming potential, Lenovo has promised the ability to navigate...

Project Tango is the star here when it works properly, the design is top notch and build quality is stellar. The screen is absolutely amazing for media consumption.

Project Tango is still in its infancy and this first consumer device is going to have some bugs and issues... also no USB Type-C.

First generation consumer devices are always a risk and Phab 2 Pro is far from being a perfect device, but it has potential. There are certainly some software bugs with Project Tango and some of the Tango apps. Some Android apps, like Google+, just...

Tango is a lot of fun – when it works ; Big, sharp display is great for apps and media ; Price is totally reasonable considering the hardware ; Fast recharge times

Unwieldy size ; Tango still needs a lot of debugging ; Unclear market: is this supposed to be a daily driver ; Aging Marshmallow software ; Poor notification support

The Phab 2 Pro is a hugely ambitious handset, and while it gives us a one-of-a-kind smartphone experience thanks to its Tango hardware, we just can't shake the feeling that a phone like this isn't quite ready for prime time.
